The Characteristics Analysis of Pumpforexcluding Salt-water Based on Fluid-thermal-structural Coupling
摘要
Abstract
To obtain the structural strength of the pump for excluding salt-waterat actual working condition,the steady numerical simulation of whole flow field at multi-conditions have been calculated. The one-way fluid-thermal-structural coupling of stationary parts was performed base on ANSYS Workbench. The temperature field,the maximum equivalent stress and the strain distribution are obtained under different conditions. The results show that in the pump for excluding salt-water,the inducer's temperature is the highest,and the maximum temperature appears on the inducer blade at each working condition; the maximum equivalent stress appears at the outlet of impeller (the border of back shroud and low pressure side of blade outlet), which is less than the tensile strength of the material;The maximum deformation distribution on the impeller is more uniform, appearing symmetric distribution center and the deformation of the same radius on value is the samebasically,But at the outlet of the impeller,the displacement between the two blades is larger than that of the same radius.关键词
